DETACHABLE ARCH-FILE.

SPECIFICATION forming part of Letters Patent No. 538,605, dated April 30, 1895.

Application filed April 16, 1894. Serial No. 507,643. (No model.)

To all whom it may concern:

Be it known that I, CHRISTIAN H. SToELT- ING, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Detachable Arch- Files; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The object of this invention is to provide devices for use in connection with temporary binders for loose sheets, by means of which said sheets may be rearranged and one or any number of sheets inserted or removed at any point in the temporary volume, as desired.

Temporary binders, of the class in connection with which my improvements are intended to be used, comprise two parallel filing wires upon which the sheets are filed or strung, and two cross-bars or plates connecting the wires; one of said bars being rigidly attached to the wires and holding the same in rigid position relative to each other, and the other bar or plate being movably mounted on the wires and being provided with or attached to some form of locking device by means of which it may be clamped to the wires in any position desired.

In its broad aspect my improved transfer device for use with such temporary binders, comprises a base upon which two arched filing wires are movably mounted in such manner that their straight or shank portions are constantly maintained in fixed parallel relation to each other at a distance apart equal to the distance between the filing wires of the said temporary binders, while at the same time either the arches as a whole, or the arched portion thereof, are capable of movement relatively to the base, so that when the device is brought into operative relation to the temporary binder the free ends of the arches will normally engage or stand in close lineal proximity to the ends of the filing wires of the temporary binder, but may be disengaged or separated therefrom, when desired, without disturbing the relation between the temporary binder and the base of the transfer device;

in the appended claims, and will be readily understood from the following description of aconstruction embodyingitin oneform,taken in connection with the accompanying drawings illustrative thereof, in which- Figure 1 is a plan view of a transfer device of the nature referred to,-showing a temporary binder in operative relation thereto. Fig. 2 is a similar View with the arched transferwires thrown back away from the filing-wires of the temporary binder. Fig. 3 is a sectional side elevation taken on line 3 3 of Fig. 1. Fig. at is the detail of a guide-strip. Fig. 5 is a perspective view of the device shown in Fig. 1. Figs. 6, 7, 8, 9, 10, and 11 show modified forms of various details.

A designates the base of the transfer device, consisting in this instance, of a hollow casing having upper andlower walls Aand A separated at their ends by filling pieces A and provided, as herein shown, with opposite apertures within which arched filing wires B are rotatively mounted with their straight or shank portions arranged parallel from the base. Suitable devices are provided within the base A for limiting and controlling the rotary movement of the wires 13, consisting in this instance of radial arms 17 rigidly attached to the wires and engaged at their outer endsby the free ends of a suitable spring a. The filling pieces A act as stops to limit the outward movement of the arms 6 and wires B, while suitable stop pins a serve to limit their inward movement in such manner that when the arms Z) are pressed by the spring a against the stops at the arched portion of the wires as well as the shanks thereof will be parallel to each other. Obviously, however, any other suitable devices for limiting and controlling the movement of the wires B, either independently, as herein shown, or conjunctively, as is often the case in devices of this character, may be provided Without affecting the important features of my invention.

G designates a temporary binder of a usual construction, comprising in this instance a lower sheet support or cover C, to which parallel filing wires C are rigidly attached a their lower ends at a distance apart equal to the distance between the wires B of the transfer device. An upper crossbar or cover 0 is perforated to slide freely on said filing wires C and is provided with a suitable locking device C by which it may be clamped in any desired position on said wires; the locking device shown in this instance being that setforth in the patent to Copeland and Chatterson, No. 448,411, dated March 17, 1891, although any other locking devices may be employed. Any number of loose sheets S are adapted to be filed or strung upon the tiling wires C between the covers 0' and C and the whole forms, when the upper cover is clamped down in place, a temporary volume adapted to be handled in the same manner as an ordinary book.

As one convenient and desirable means for temporarily and detachably engaging the base A of the transfer device with the temporary volume in such manner as to bring the free ends of the transfer arches B when in their closed or parallel position, directly above and in close proximity to or engagement with the free upper ends of the filing wires C an overhanging ledge A is formed or provided on the base A directly beneath the free ends of the arches B, said ledge being adapted to be thrust between the lower cover 0 of the temporary volume and the loose sheets S thereof. Such ledge is in this instance formed by the projecting edge of the upper plate A of the base A and is cut or provided with suitable marginal slots at which receive the filing wires 0 and serve to guide the same beneath the ends of the arches B. Various forms of slots may be used for this purpose. In Fig. 2 I have shown a bayonet slot the ends of which are directly beneath the free ends of the wires B, and in engaging which the temporary volume is first thrustdirectly toward the base A until the cover 0 passes beneath the ledge A and the wires (1 enter the months of the slots a and is then moved laterally to bring the wires G 'into engagement with the ends of the arches B. The slots in the ledge A may, however, be merely straight slots extending perpendicularly inward from the edge of the ledge, as shown at a in Fig. 7, or may even be mere V-shap'ed notches, as shown at a in Fig. 6 or may be otherwise variously constructed so long as their principal function of receiving the wires (J and guiding the same beneath the arches Band of holding the temporarybihder from V lateral movement with relation to the base A,

when the parts are brought into operative re lation, is provided for. A base plate A to which the base A is rigidly secured by screws a serves also in this instance to aid in locating the temporary binder with respect to the transfer device; the temporary volume restin securely on said base plate and the lower cover 0' thereof being made of such thick ness as to be compressed or pinched between the ledge A and the base A with a considerable degree of friction.

For the purpose of securing an easily detachable but positive engagement between the upper ends of the wires C and the free ends of the arches B, the latter are herein shown hollowed out at their ends to receive the ends of the wires 0 which are pointed for this purpose. In this case the naturalspring or resilience of the wires B will permit the same to be lifted olT of the wires C when it is desired to swing the arches apart, or to separate the binder from the transfer device. Any other convenient or suitable form ofconnecting the ends of the filing wires to the if desired, as for instance, I have shown in transfer arches may, however, be provided, Fig. 8 a construction in which the filing wires C are made hollow and are cut off on an angle at their upper ends, while the ends of the arches B are pointed to enter the hollows of the beveled ends so formed.

In Fig. 9 I have shown astill further modification in which the ends of the arches and filing wires are rabbeted so as to brealtjoints when brought into engagement with each other. In general it will be obvious that so far as this detail of construction isconcerned all the modifications are intended to provide a connection between the arched transfer wires and the filing wires which will be practically co..tinuous and as smooth as possible when such parts are broughtinto engagement and at the same time will be capable of being readily disconnected when it is desired to separate the parts.

In case the resilience of the arches is not suificient to permit the disengagement of the ends thereof from the filing wires C said arches B may be connected with the base by means which will permit a bodily upward and downward movement of said arches. Such a device is illustrated in Fig. 10. Here the shanks of the arches B are mounted to slide longitudinally within tubular sleeves B rigidly secured in the base-A and which are provided with vertical slots 1') opening at their ends into transverse slots 19?. Pins 12 projocting from the wires B engage said slots and control the movement of the arches, and a tension spring 17, secured to the lower ends of the wires B and to the casing within the sleeves '1), tends to draw said wires clown- ICO the temporary binder, in the manner before described.

In order to prevent the mutilation of the edges of the lower sheets S by the ledge A when the lower cover 0' is thrust beneath the same, 1 have in this instance provided a metallic guard-strip C positioned between the cover 0' and the lowermost of the sheets S in such manner as to lie between the ledge and the lowermost sheet when the parts are brought into engagement. Said strip is in this instance secured by being perforated to slide freely on the wires C and is provided with an upturned outer edge 0 projecting slightly beyond the rear edges of the leaves S, and by reason of which the strip is forced upward by the ledge when the cover 0 is passed beneath the latter.

With the construction thus described it will be obvious that whenever it is desired to rearrange the loose sheets secured in a temporary binder, or to insert or remove one or more sheets at any point thereof, it will only be necessary to bring the temporary binder into operative relation with the transfer device, as for instance, in the present example, by thrusting the lower cover 0 beneath the ledge A and bringing the wires C directly beneath and in engagement with .the free ends of the arches B. The locking device C being then released, the cover C together with as many of the loose sheets S as may be desired, may be thrown over on to the shanks of the arches B. When the sheets have been separated at the proper point the arches B may be swung apart in the manner usual upon files employing such arches, whereupon the upper ends of the wires C will obviously be left free to receive or permit the removal of any number of sheets as desired. The arches Bmay then be swung back into their parallel position, and into engagement with the filing wires 0 The sheets and cover upon the shanks of the arches may be returned to their position in the volume, and said cover clamped down to complete the volume, as before. Obviously a repetition of this manipulation will enable the sheets to be redistributed, or their number increased or diminished to any desired extent. When such manipulations have been completed the temporary volume may again be separated from the transfer device and will be in condition to be handled in the same manner as an ordinary book, or as other temporary volumes of the same general character.

It will be understood that while the devices herein shown for'effecting a temporary and detachable connection by which the temporary binder and the arched filing wires are maintained in operative relation with respect to each other, are convenient and approved constructions which in themselves involve features of novelty and are hereinafter claimed, any manner of device by which said connection may be effected will beincluded within the spirit of my broadinvention. Furthermore, while temporary binders of the nature referred to may be sold in connection with improved transfer devices as a complete article, the transfer device is adapted to be made up as a separate article of manufacture and sale, to be used in connection with any be found adapted.
